Fuel Injection Rail problems of the 2006 Mini Cooper S

Brand new vehicle was towed in for repair at 7,308 miles 1/27/10 vehicle was brought in for service due to misfires 1/27/810. Mini service cleaned fuel system and provided "curtesy" first time injector service. Vehicle was returned to me and brought back the next day for the same misfire faults 2/2/10, high pressure fuel pump was replaced and fuel rail was removed. 7,318 miles, 10 miles later. . . The vehicle was towed in again for combustion misfires 24,491 miles 8/12/11 brought vehicle in for strange noise, Mini said it was nothing to worry about. 24,783 miles 8/18/11 vehicle was towed in due to engine seizing. . . Turbo carbon build up, turbo feed line issues 33,124 miles 01/31/12 vehicle was making noises, brought in to service, Mini said they would need to inspect the car closer to see what was going on. I scheduled a service and loaner for 2/1/12 (report said that there were misfire issues, I was not informed. . . Until I noticed it on the report a week later) 33,250 miles 2/1/12 vehicle was towed in engine seized, engine completely replaced. Mini claims that this is not a lemon in any way and that I will need to continue to pay for my lease until the contract end. I feel unsafe driving a car, with a track record of seizing or misfiring at any time on a highway or road, putting me in a very dangerous situation.
